(September 4, 2009 - Insidermedicine) From San Francisco - Scientists have discovered antibodies that prevent HIV from becoming severe AIDS, according to a report published in the journal Science. Researchers examined the blood samples of over 1800 people who had HIV for at least three years and had not yet experienced progression of their infection. They found that two antibodies, PG9 & PG16, effectively prevented 162 different strains of HIV from multiplying and developing into severe disease. Scientists believe this discovery could potentially lead to an AIDS vaccine. From Illinois - According to a report published in the journal Obesity, late-night eating can lead to weight gain.  Researchers fed two groups of mice at different times of the day; one ate when they would typically be sleeping, while the other ate at their regular feeding time. Even though both groups exercised the same amount and were fed equal portions of food, the group that ate late gained twice as much weight. And finally, from Washington - According to research from the American Institute for Cancer Research and the World Cancer Research Fund, a healthy lifestyle could help prevent a woman's risk of breast cancer. Researchers analyzed nearly 1000 studies that examined the links between lifestyle and breast cancer. Their analysis revealed that roughly 40% of breast cancer cases per year could be prevented with exercise, healthy weight, reduced alcohol consumption and breastfeeding.
